I've seen far less of this than most of you. But from what I have seen, definitely Kate. She's the obvious choice, but SAS being SAS (Dewberry over Badger) and TV being TV, that's just not good enough and so she is "too perfect" and she'll probably lose. Safe choices aren't really what makes for the best TV and SAS likes to be a bit of a showman.

Despite the fact that they all get put into run of the mill executive jobs and none will ever really become his true Apprentice, he still seems to hire as though he was searching for a bit of a maverick that could follow in his footsteps.
